Your Dyson machine is programed to remind you to replace the filter unit after 12 months based on 12 hours usage a day. Please note your indicator will activate sooner with more use. The indicator is only a guide and you may need to replace the filter unit more regularly.
How to replace the filter
Your replacement filter may come as one part (outer housing and inner filter are attached together), two parts (outer housing and inner filter are separate), or one inner filter. The two part filter has arrows inside the unit.
If you have received one part where the housing and inner filter are attached, install the new unit and dispose of the previous unit.
If you have received two parts, and previously had one part, dispose of the old unit and install both the outer housing and inner filter. In future, you will only have to replace the inner filter.
If you have received one inner filter, and currently have the two part filter installed, install the new inner filter and dispose of the previous one.
One part filter
Please follow the steps in the video.
Two part filter and inner filter

Machine is working normally
This is completely normal.
The machine will run very slowly when in idle mode to keep air flowing over the thermostat so it can constantly regulate the temperature of the air.
There is no safety concern.
If the noise is intrusive, switching the machine off at the wall will stop the noise, or altering the position of the product in the room might make the noise less audible.
If pressed, it should be stated that the noise is caused by some of the electrical components emitting a frequency which can sometimes be heard as an electrical humming noise. This is not specific to Dyson products.
We're glad the problem's been solved.
Please let us know if there's anything else we can help you with.

Target temperature
The heater will not operate unless the target temperature is above the room temperature. The temperature set on the machine is the target temperature of the room, not the temperature of the fan; the temperature from the fan when in heating mode will not change.
Press the red temperature control button until the digital display on the Main body shows 37°C.
Dyson Pure Hot + Cool Link is intended for use as a domestic heater, fan and purifier. IEC 60879 Performance and construction of electric and circulating fans and regulators states that the distance over which a fans airflow is felt should exceed three times its width. Dyson Pure Hot + Cool far surpasses this requirement.
Paper test
Turn the airflow control to maximum.

Hold a sheet of newspaper approximately 4 meters (13') away from the product.
The paper should lift beyond 45 degrees.

More than nine hours
Dyson fan heaters and hot and cool purifiers have a positive safety feature where the machine deliberately switches off after 9 hours of continuous heating.
If you would like to continue using the machine after 9 hours, you will need to turn the machine back on by using either the power button on the remote control or Main body.
This would also occur if the machine is set to auto and providing heat constantly for 9 hours.
NB: This feature cannot be switched off

Please select the appropriate option
Cooling mode
Press the blue Cooling mode button to enter Cooling mode.

How to use the heater mode
Press the red thermostat control button until the digital display shows the target room temperature.

The power button light will change from blue to red to indicate that you have entered heating mode.

To adjust the airflow speed use the airflow control button or use auto purification mode for automatic control.

On first use the purifier will default to a temperature 3 degrees Celsius higher than the detected room temperature. Thereafter, the purifier will remember the last target temperature.
Target temperature indicator
- The target temperature indicator will be red while heating and once the target temperature has been reached, the purifier will stop heating the air.
- The target temperature indicator will change to white when the target room temperature has been reached.

Auto purification mode
Auto purification mode adjusts the airflow speed according to the air quality in the room.
When enabled (indicated by a white A symbol in the bottom left corner of the display), the on-board sensors will intelligently adjust the speed of the purifier according to the air quality. Increasing for poor air quality and reducing as the air quality improves.

Auto purification in cooling mode
If the air quality target is met, the A symbol will turn green and the numbered display will switch off.

If the air quality worsens the A symbol will turn white and the purifier will automatically restart cleaning the room.

Auto purification in heating mode
The display indicates that the air quality and room temperature are below target; the appliance is heating and purifying the air.
The purifier will display the target room temperature, not the fan airflow.

The display indicates that the air quality is below target but the target room temperature has been met.

The display indicates that the air quality has been met but it's below the target room temperature.
The appliance will continue heating until the target temperature is met.

The display indicates that the air quality and room temperature targets have been met.
